From the application perspective of SiC single crystal growth, this article compares the basic physical parameters of TaC coating and SIC coating, and explains the basic advantages of TaC coating over SiC coating in terms of high temperature resistance, strong chemical stability, reduced impurities, and lower costs.

This article describes that LED substrate is the largest application of sapphire, as well as the main methods of preparing sapphire crystals: growing sapphire crystals by the Czochralski method, growing sapphire crystals by the Kyropoulos method, growing sapphire crystals by the guided mold method, and growing sapphire crystals by the heat exchange method.

With the development of the solar photovoltaic industry, diffusion furnaces and LPCVD furnaces are the main equipment for the production of solar cells, which directly affect the efficient performance of solar cells. Based on the comprehensive product performance and usage cost, silicon carbide ceramic materials have more advantages in the field of solar cells than quartz materials. The application of silicon carbide ceramic materials in the photovoltaic industry can greatly help photovoltaic enterprises reduce auxiliary material investment costs, improve product quality and competitiveness. The future trend of silicon carbide ceramic materials in the photovoltaic field is mainly towards higher purity, stronger load-bearing capacity, higher loading capacity, and lower cost.

Chemical vapor deposition (CVD) in semiconductor manufacturing is used to deposit thin film materials in the chamber, including SiO2, SiN, etc., and commonly used types include PECVD and LPCVD. By adjusting the temperature, pressure and reaction gas type, CVD achieves high purity, uniformity and good film coverage to meet different process requirements.

The chip manufacturing process includes photolithography,etching, diffusion, thin film, ion implantation, chemical mechanical polishing, cleaning, etc. This article roughly explains how these processes are integrated in sequence to manufacture a MOSFET.

Silicon carbide (SiC)'s Key growth methods include PVT, TSSG, and HTCVD, each with distinct advantages and challenges. Carbon-based thermal field materials like insulation systems, crucibles, TaC coatings, and porous graphite enhance crystal growth by providing stability, thermal conductivity, and purity, essential for SiC's precise fabrication and application.
